A number of animal and plant populations have been seen to decline or, in some cases, have become extinct over recent decades. There are a number of reasons for this and there are also significant knock-on effects related to these ecological changes. However, there are potential solutions as this essay will explain.
Human activity has in the most part led to such changes in the natural world. For example, many species of flora and fauna has been negatively affected due to deforestation activity in tropical rainforest areas. In some cases, this change in environment has made it extremely difficult or impossible for certain species to survive. The survival of certain animal populations has also come under threat due to over-hunting, particularly when such species are considered to be a delicacy or to have healing properties. This situation has led to massive decline in bear populations, for example, in certain parts of the world.
The loss of such plants and creatures is significant as the ecological cycle is interlinked and the decline of one population may adversely affect another, if it were its food source, for example or if it has a positive impact on the eco-system as a whole.
In order to protect our world and its inhabitants, we need to become more aware of the effects of our actions and the long-term repercussions. While activity such as forestry is necessary it should also be sustainable. Over-hunting of species should be monitored on an international level.
